PCI Express® Card Edge Connectors

These 1.0mm pitch, vertical card edge connectors from AFCI enable all generations of PCI Express® signaling in desktop PCs, workstations, and servers. The connector designs provide support for 2.5Gb/s (Gen1), 5.0Gb/s (Gen2), and the recent update to 8.0Gb/s (Gen3) per differential signal pair.

The base connector family provides x1, x4, x8, or x16 link widths to suit different bandwidth requirements. The basic bandwidth (x1) version supports a single PCI Express lane and is typically used for I/O cards in desktop PCs. The x4 and x8 connectors provide 64 and 98 contacts, respectively, for server I/O. The high bandwidth versions (x16 lanes and higher) are used for applications that require even more bandwidth, such as graphics cards in desktop PCs or riser cards in servers.

AFCI’s expansive range of available PCI Express card edge connectors includes options for through-hole solder, press-fit, surface-mount, or straddle-mount termination.
